[Form] Automatically add step attribute to HTML5 time widgets to display seconds if needed

Same issue as #9976 and #10203: when you add a `time` field to a form with options `single_text` (so HTML5) and `with_seconds`, the generated input does not contain the `step` attribute, therefore the browser does not show them, leading to an error at the submit because of an invalid format.

Compared to #9976/#10203:
* Unit testable
* Available directly in the component
* Available in other templating format than twig
* Still able to customise the step attribute by hand
